wideband sensors

I own a 1997 Subaru Impreza WRX STI version 3. I'm looking at fitting a wideband sensor for tuning purposes and also to possibly feed the ecu with the narrowband signal. What recommendations do people have? I've notices the latest wideband sensor seems to be the LSU ADV. Is this now the preferred sensor to use? Looking at the LD performance wideband controller. Cheers.

Hi Paul,

What ecu are you using? My preferred method is to use a CAN based wideband system and have this feed direct into the ecu.

Most of these systems come with the LUS 4.9 sensor although some still run the 4.2

On my dyno I use a MOTEC PLM with an NTK Sensor and for my road test/tuning I use a Innovate LM2 with a LSU 4.9 if there is no Lambda to CAN.

I try not to use any analogue input signals from a wideband gauge as these are pretty inaccurate and can be influenced easily with wiring issues.

Hi thanks for the reply. I'm using an enduring solutions ECU. This enables remapping of the standard ECU. I'll probably leave the standard narrowband sensor in place to feed the ECU it's required signal if the wideband analogue output is inaccurate. Do you know much about the new generation of wideband sensors (adv)? They're advertised as the preferred choice in Motorsport.

Hi Paul,

If you're working on a stock ecu then I would keep the stock narrow band into the ecu as the calibration in the ecu will be matched to the narrow band.

However, for tuning you need a wideband to get the correct readings.

I have not used the new LSU ADV range, hope someone here has and can have some feed back on this.

Ok thanks mate.
